Automated Birthday email
once you put in a persons birthday on their contact sheet you should be able to set it to send an email automatically. You would create your own templates to choose from for it. then just set it and forget it. Even on a Sunday or when you're on vacation, your birthday wishes would be going out to your contacts. They would love you for it!
